Video Advertising – one of the oldest inventions of mankind.

As well as using audio resources to inform mass audiences. From the time the heralds of ancient Babylon and Rome and medieval heralds specifics.

Have you tried to watch TV without sound? Not very interesting to do, to put it mildly. Street TV without sound – not quite TV. While outdoor advertising were static, some special needs in the sound did not arise. With the advent of LED screens reproducing dynamic video, the need for an audio downright suggests itself.

However, it turned out that is not so simple. Firstly, in contrast to the TV, the playback sound volume in a limited space, the organization of the video monitor soundtracks, with its vast reach, the engineering is a difficult task. Secondly, there are certain legal restrictions on the maximum volume of the audio source in the city, so just provide the screens with powerful speakers do not always succeed. Organization of surround sound installation, for example, along the perimeter of the zone sets of speakers screen also is very difficult. In the most “delicious” crossroads, where video screens are excellent indicators for the audience, the level of acoustic noise from urban transport and other sources may be such virtually impossible. Also much enthusiasm by the appearance of powerful sources of sound advertising do not show the people and municipal authorities.

Therefore, to date audio broadcast system is equipped with no more than 2% of outdoor advertising screens. And this despite the fact that the recent marketing studies show that adding audio to digital displays and screens increase the motivation of potential consumers by as much as 40%.

As technology advances, the situation began to change for the better. Displays and screens getting bigger. Accordingly, there are more decisions associated with the implementation of a sound channel.

In fact, what could be more inefficient than the television broadcast on the public display without sound? How often you can see people staring at the TV without sound from the airport or a bar?

That is why there are companies that offer the type of AudioStreamTV HearMyLips or applications that can be used to connect a synchronous sound to your mobile app and listen to the broadcast, without interfering with others.

Of course, we must not forget that in a bustling modern city of audio connection can only further “litter” background sound effects and instead of advertising people just act on the nerves. That is why the use of sound coverage must be considered, the distance from which one can hear the sound correctly combine video and audio content, so that they complement each other.

We should not forget about security measures on the network, as well as the possibility of remote monitoring of what is happening. The fact that modern digital outdoor video systems can be used not only for commercial advertising purposes, but also as a public broadcasting system, for particular emergency warning, or for large-scale cultural and social projects.

Thus, for example, the street turns into a video screen and to a multifunction information device with a public order functions and monitoring of the environment, the ability to connect interactive features, the ability to broadcast information loud in case of emergencies.

In other words, the union of LED screens and audio broadcast is an untilled field of possibilities. In what direction it will plow? We will see very soon.
